Where can i set a setting to show the Indicator showing a file is not saved/ or being edited?For example, in all other common editors:

non-saved.png (21.43 KiB) Viewed 846 times

There are Asterisks (*) on where we can easily know which files are not yet saved/ being still edited.It is something very important basic function in every common editors. ORNo such feature in Sublime???

If "no", how can i know which files are Saved one and which are Non-Saved ones???
